May impair fertility.
Possible risk of harm to the unborn child.
Toxic in contact with skin and if swallowed.
Risk of explosion if heated under confinement.
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED! Toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 40 gram may
be fatal or may produce serious damage to the health of the individual.
! The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.
! After oral dosing of hexafluoroacetone in rats, moderate to severe CNS depression persisting for several days was noted. No other signs
were discernible. On gross necropsy, no abnormalities were evident.
EYE! The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating.
! If applied to the eyes, this material causes severe eye damage.
! Undiluted hexafluoroacetone sesquihydrate was instantly painful and produced a severe extensive injury in the rabbit eye. When rinsed
with water 20 seconds after instillation, the eye appeared to return to normal 29 days after exposure except for a small corneal injury with
local vascularisation. The unwashed eye showed extensive corneal opacity, scar tissue, pannus, and chronic conjunctivitis.
SKIN! Skin contact with the material may produce toxic effects; systemic effectsmay result following absorption.
! The material can produce chemical burns following direct contactwith the skin.
! Undiluted hexafluoroacetone sesquihydrate is a severe skin irritant as expected by its acidic (pH = 1) nature. Concentrations below 50%
produced mild to no irritation on rabbit skin. The irritation response at higher concentrations included definite erythema that became scaly
and developed crusts 1 to 5 days postapplication. One drop of undiluted dihydrate produced marked erythema and blanching to guinea pig
skin, but no irritation was seen with dilutions of 0.1 to 10%.
After dermal application, there was no measurable amount of material remaining on the skin of the rabbits at the end of the exposure period.
The exposed area was erythematous and scaly and developed crusts (eschar formation) 2 to 5 days after exposure. Mild CNS depression
preceded death, but no other abnormal signs were evident. On gross necropsy, no abnormalities were present except for discolouration and
oedema of the exposed skin.
! Fluorides are easily absorbed through the skin and cause death of soft tissue and erode bone. Healing is delayed and death of tissue may
continue to spread beneath skin.
! Open cuts, abraded or irritated skin should not be exposed to this material.
! Solution of material in moisture on the skin, or perspiration, may markedly increase skin corrosion and accelerate tissue destruction.
! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine
the skin prior to the use of the material and ensure that any external damage is suitably protected.
INHALED! If inhaled, this material can irritate the throat andlungs of some persons.
! The material is not thought to produce adverse health effects following inhalation (as classified using animal models). Nevertheless,
adverse effects have been produced following exposure of animals by at least one other route and good hygiene practice requires that
exposure be kept to a minimum and that suitable control measures be used in an occupational setting.
! Symptoms of exposure may be burning sensation, coughing, wheezing, shortness of breath, headache, nausea, vomiting. An acute severe
inhalation exposure may be fatal as a result of spasm, inflammation and edema of larynx, chemical pneumonitis and pulmonary oedema.
For hexafluoroacetone dihydrate, the maximum concentration causing irritation of the upper respiratory tract was reported to be 32 mg/m3
(equivalent to 26 mg/m3 hexafluoroacetone).
After inhalation exposure by rats, depression of the central nervous system (CNS) was manifest as hind leg instability and loss of postural
and righting reflexes . The effects persisted for several hours. Most of the fatalities occurred 2 to 6 days after exposure. There was little, if
any, lung damage. There were no
histological findings in heart, kidney, or liver.
! Acute effects of fluoride inhalation include irritation of nose and throat, coughing and chest discomfort. A single acute over-exposure may
even cause nose bleed.
<\p>.
CHRONIC HEALTH EFFECTS! Repeated or prolonged exposure to corrosives may result in the erosion of teeth, inflammatory and ulcerative changes in the mouth and
necrosis (rarely) of the jaw. Bronchial irritation, with cough, and frequent attacks of bronchial pneumonia may ensue.
<\p>.
Ample evidence exists from experimentation that reduced human fertility is directly caused by exposure to the material.
Results in experiments suggest that this material may cause disorders in the development of the embryo or fetus, even when no signs of
poisoning show in the mother.
Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or
2 of 13
biochemical systems.
Animal testing with the gas at 12 ppm for rats and dogs (13 weeks @ 6 hour) showed testicular degeneration and atrophy, hyperglycaemia,
anemia.
In reproduction toxicity studies in which pregnant rats were exposed during organogenesis, minimal but statistically significant decreases in
female offspring body weight were seen at exposure by inhalation to 0.76 mg/m3, and a higher incidence of hydronephrosis, one
anophthalmic foetus and 2 stunted fetuses at a dermal dose of 0.75 mg /kg bw , the lowest concentration/dose tested.
Hydrogen fluoride easily penetrates the skin and causes destruction and corrosion of the bone and underlying tissue. Ingestion causes
severe pains and burns in the mouth and throat and blood calcium levels are dangerously reduced.

----------------------------------------------------------------------------------------------------------------
" Establish a patent airway with suction where necessary.
" Watch for signs of respiratory insufficiency and assist ventilation as necessary.
Following acute or short term repeated exposure to hydrofluoric acid:
" Subcutaneous injections of Calcium Gluconate may be necessary around the burnt area. Continued application of Calcium Gluconate Gel
or subcutaneous Calcium Gluconate should then continue for 3-4 days at a frequency of 4-6 times per day. If a "burning" sensation recurs,
apply more frequently.
" Systemic effects of extensive hydrofluoric acid burns include renal damage, hypocalcemia and consequent cardiac arrhythmias. Monitor
hematological, respiratory, renal, cardiac and electrolyte status at least daily. Tests should include FBE, blood gases, chest X-ray, creatinine
and electrolytes, urine output, Ca ions, Mg ions and phosphate ions. Continuous ECG monitoring may be required.

Section 11 - TOXICOLOGICAL INFORMATION
HEXAFLUOROACETONE HYDRATE
TOXICITY AND IRRITATION! unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
! Asthma-like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non-allergenic
condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating
compound. Key criteria for the diagnosis of RADS include the absence of preceding respiratory disease, in a non-atopic individual, with abrupt
onset of persistent asthma-like symptoms within minutes to hours of a documented exposure to the irritant. A reversible airflow pattern, on
spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine challenge testing and the lack of minimal
lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or asthma) following an
irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating substance.
Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating substance (often
particulate in nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus
production.
HEXAFLUOROACETONE:
HEXAFLUOROACETONE HYDRATE:
! Exposure to the material for prolonged periods may cause physical defects in the developing embryo (teratogenesis).
! In subchronic inhalation studies, intermittent exposure to 6.9 mg/m3 hexafluoroacetone caused reversible kidney dysfunction and increased
relative lung weight in rats and dogs, respectively. This concentration did not induce testicular effects in rats. In separate reproduction toxicity
studies in which pregnant rats were exposed during organogenesis, minimal but statistically significant decreases in female offspring body weight
were seen at exposure by inhalation to 0.76 mg/m3, and a higher incidence of hydronephrosis, one anophthalmic foetus and 2 stunted fetuses at
a dermal dose of 0.75 mg /kg bw, the lowest concentration/dose tested.
Pregnant rats (n=24/group) were exposed to hexafluoroacetone concentrations of 0, 0.76, 6.9, or 48 mg/m3 (0.11, 1, 6.9 ppm), 6 hours/day, on
gestational days 7 through 16. On gestational days 17 to 22, maternal weight gain in the high-concentration group was less than in the control
group (p<0.05). This was attributed to embryolethality and an adverse effect on fetal weight in this group rather than to maternal toxicity. The
mean number of live fetuses per litter was significantly decreased and the number and percentages of total and later resorptions were
significantly increased in the high-concentration group. Late resorptions were also slightly, but significantly increased in the mid-concentration
group. It is not clear whether the increase in late resorptions at the mid concentration is a compound-related effect. The weights of male, female,
and combined fetuses were significantly lower than controls in both the mid- and high-concentration groups.
Malformations were significantly increased at the high concentration, and included increases in anasarca (subcutaneous oedema) and cleft soft
palates. External developmental variations (oedema and subcutaneous haemorrhages) were also significantly increased in the
high-concentration group. Skeletal variations consisting of extracervical and lumbar ribs were significantly increased at the mid and the high
concentration. Variations due to retarded development, primarily delayed ossifications of the skull, vertebrae, ribs, and sternebrae were
increased at the high concentration The maternal NOAEL was 0.76 mg/m3. A NOAEL for the conceptus could not be established. Based on a
minimally decreased body weight in female foetuses, it was concluded that 0.76 mg/m3 (0.11 ppm) ( the lowest concentration tested) is a lowest-
observed-adverse-effect level (LOAEL) for developmental effects in rats.
Male rats were exposed to hexafluoroacetone concentrations of 0, 0.7, 6.9, or 83 mg/m3 (0, 0.1, 1, 12 ppm), 6 hours/day, 5 days/week, for 90
9 of 13
days (n=40/group).
After 30 days of exposure to 83 mg/m3 (12 ppm), rats showed lower body weight gain, testicular atrophy, and oligospermia or aspermia in the
epididymal tubules. At 90 days of exposure, the testes showed severe atrophy with almost all seminiferous tubules affected. After a 28-day
recovery period, regeneration of atrophic testes was evident but varied markedly among the exposed rats. At 84 days postexposure,
spermatogenesis was still only partially restored. It can be concluded that inhalation exposure to 6.9 mg/m3 (1ppm) is an NOAEL for testicular
effects in rats. In another study with the sesquihydrate, similar findings were reported. Histological evaluation of the testes revealed that
spermatids followed by spermatocytes were the germ cells mostly affected; spermatogonia and Sertoli cells appeared to be less vulnerable.
Possibly the altered lipid metabolism, in particular sterol metabolism, is associated with the development of hexafluoroacetone-induced testicular
atrophy.
Hexafluoroacetone dihydrate was not mutagenic in the Ames assay, using S. typhimurium (no details presented) Hexafluoroacetone
sesquihydrate was not mutagenic in the Ames assay, using S. typhimurium strains TA97, TA98, TA100 and TA1535, with and without rat- and
hamster-liver metabolic activation.

Section 13 - DISPOSAL CONSIDERATIONS
US EPA Waste Number & DescriptionsB. Component Waste Numbers
When hydrogen fluoride is present as a solid waste as a discarded commercial
chemical product, off-specification species, as a container residue, or a spill
residue, use EPA waste number U134 (waste code C,T).
Disposal InstructionsAll waste must be handled in accordance with local, state and federal regulations.
$ Puncture containers to prevent re-use and bury at an authorized landfill.
Legislation addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws
operating in their area. In some areas, certain wastes must be tracked.
A Hierarchy of Controls seems to be common - the user should investigate:
" Reduction
" Reuse
" Recycling
" Disposal (if all else fails)
This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. If it
has been contaminated, it may be possible to reclaim the product by filtration, distillation or some other means. Shelf life
considerations should also be applied in making decisions of this type. Note that properties of a material may change in use, and
recycling or reuse may not always be appropriate.
DO NOT allow wash water from cleaning equipment to enter drains. Collect all wash water for treatment before disposal.
" Recycle wherever possible or consult manufacturer for recycling options.
" Consult Waste Management Authority for disposal.
